The stomach bug stuck crept back, and stuck with me, so I decided to take the day off.
The day 159 meditation talks about preliminaries to asana practice. There are basically two words of advice here. First, set your intention. This is something that we get told all the time at the start of Bikram practice. Second, Gates says you can do this with a simple short prayer. The prayer will help acknowledge your place in the universe. He uses either "Thy will be done." or "Thank you for bringing me here."
I've taken recently to doing something similar before the long savansana after standing series. But when we are told to "set your intention," I mostly just stare blankly at myself in the mirror. The pause and short word of thanks after standing series has worked really well for me. And this is not much different and has almost zero cost. So I will definitely be giving this a try. I'm kind of amazed that I hadn't thought of this before.
